The WS-PCS2250-2 is a high-power utility-scale Power Conversion System designed for large-scale battery energy storage systems (BESS). It integrates bi-directional AC/DC conversion, PV inverter functionality, and grid-forming capability into a single 10ft compact container. Ideal for peak shaving, microgrids, VPP, and hybrid diesel-PV-storage applications.
Frequently Asked Questions
Q1: Is the WS-PCS2250-2 a battery or an inverter?
A: It is a PCS – a bidirectional power converter that connects batteries to the grid, loads, and PV arrays. It performs both inverter (DC to AC) and rectifier (AC to DC) functions.
Q2: Can this PCS work without PV input?
A: Yes. The PV inputs are optional. The PCS can operate purely as a battery energy storage inverter using only the battery DC terminals.
Q3: What battery voltage range does it support?
A: It supports a 630Vdc to 1000Vdc battery input voltage, compatible with most utility-scale LFP battery racks.
Q4: Does it support off-grid operation?
A: Yes. It supports on-grid, off-grid, and microgrid modes, including seamless transition between grid-tied and islanded operation.
Q5: What is the IP rating?
A: The WS-PCS2250-2 has an IP54 ingress protection rating, suitable for outdoor installation with protection against dust and splashing water.
Q6: Can multiple units be used together?
A: Yes. The system is designed for modular scalability – multiple WS-PCS2250-2 units can be paralleled for larger energy storage projects.
